Here, here!


Amith Varghese <amith at xalan.com>, 2nd October too:

I'm using Imp 3.1 tarball and cyrus 1.6.25 and with the following relevant
settings in servers.php:
    'folders' => '',
    'namespace' => 'INBOX.',

With cyrus, there can be both folder levels which are folders themselves,
and levels which are not folders.

The problem is with folders outside INBOX (so called bulletin boards in
cyrus), Imp doesn't recognise folders which have subfolders in pulldown
lists. They are accessible from the Folders view, however. It the folders or
namespace setting are something different, things don't work as they should
(at all).

I fixed this by changing the following line in 3.1 Folders.php

!isset($list[$prefix . $namespace . $parent]) &&
to
!(isset($list[$parent]) || isset($list[$prefix . $namespace . $parent])) &&

Works for me. I don't understand why or how, but I don't care :)
